Depending on the type of failure, important files may be lost when you use this
equipment. Files can be lost by power failure and human mistakes during
operation in addition to the failure of the equipment. If such a situation occurs,
the files cannot be recovered. In order to prevent data loss, make it a routine to

<Precautions>
・The access performance of the HDDs differs depending on the equipment. Also note that
the performance of an HDD is lower at high or low temperatures. When you use HDDs,
confirm that the access performance of the HDDs at normal temperatures and their
degraded performance at high or low temperatures do not cause any problems to the user
application.
・Regularly replace the HDD/SSD by referencing "APPENDIX HANDLING
REPLACEABLE COMPONENTS".
<Required actions>
・Do not subject HDDs／SSDs to vibration or shock.
・Take preventive action against static electricity due to human contact, and due to other

・Do not touch the printed circuit board or the connector of an HDD/SSD. Failure to heed
this instruction might result in damage to the HDD/SSD.
・When you store an HDD／SSD for a long time, put the HDD／SSD into an anti-static
bag and then store it in a dedicated box.
